SIGHTING REPORT UFO sighting at Rt.93 south, north of BostonMA

There were three red lights in the distance flying low and in no distinct formation. The sky was cloudy but these were definitely below the cloud line. They flew directly over head of Rt.93 heading north. This is when I saw the silohuette. It was hard to tell but it was definitly black and either triangle or cigar shape. The bright red light on the bottom made it hard to distguingish. As it flew over, one of the craft turned on a green light. From a rough guess the objects were 100-200 ft. above the ground and about the size of a car possibly larger.

They flew in no distinct formation but followed the "leader's" every move. They flew sort of zig-zag, stopping and going at great speeds. I discounted the possibility of helicopters for they flew at an extremly unsafe proximity to eachother.

THIS IS FOR REAL. I've never seen so many cars almost crash into eachother. Everyone was slamming on the brakes to get a good look at it, causing a minor traffic jam. I tried to look it up this morning but nothing has been said yet. Unfortunatly I was unable to snap a picture of it, but hopefully someone else was able to. Please look into this incident and get back to me if you discover abything. Thank you.
